Petrochemicals
Continuous plants run for months between shutdowns, which makes an instrument that drifts, fouls or needs realignment worse than no instrument at all. And a large part of the plant is a classified area.
The problem
Composition is monitored by a lab loop with a turnaround measured in hours, or by an online analyser house that costs more than the unit it serves. Between readings, blend ratio and feed composition move, and the correction is applied to a plant state that has already changed.
The second problem is where the measurement has to sit. An analyser that cannot be installed in a classified area gets installed somewhere convenient instead, with a sample line long enough that what it measures is no longer what is in the pipe.
Where it bites
Blending verification
Confirm the ratio in line rather than certifying it after the fact.

- No interferometer, no moving components and no optical fibres — nothing inside to fall out of alignment during a six-month run.
- Intrinsically safe design, made possible by a 0.6 W power draw. For classified areas, ask us about the ATEX-certified spectrometer series.
- Field-tested under industrial conditions in North America, South America, Europe and Asia.
- Over 100 days of repeatability testing with no observed drift in the spectral data.
- Pressure rating 0–5 bar absolute as standard, with a 40–50 bar high-pressure version.
- Hastelloy wetted parts on request for corrosive service; SS316L, FFKM, Si, Ge and Au as standard.
A visitor at our CPACT webinar asked precisely this question — ATEX for petrochemical use. The answer is that a certified series exists; tell us the zone and we will confirm what applies.

Describe the stream, the chemistry and the decision it blocks. Where it makes sense we test the technology on your own process samples before you commit.
